The value of the expression:  [tex]\int\limits^0_3 {( x^2 + 9)^{0.5}} \, dx[/tex] will be: [tex]\frac{1}{1.5} [18^{1.5}\times 36][/tex]

We have to determine the value of the expression:  [tex]\int\limits^0_3 {( x^2 + 9)^{0.5}} \, dx[/tex]

First solving the expression without using the values of Limits:

As we can write the above as:

[tex]\int {( x^2 + 9)^{0.5}} \, dx \\\frac{1}{0.5+1}[( x^2 + 9)^{0.5+1}] \times \frac{x^3}{3} +9x[/tex]

As we know, [tex]\int{x^n} \, dx =\frac{1}{n+1}x^{n+1}[/tex], where, n is any number.

So we can write the above as:

[tex]\\\frac{1}{1.5}[( x^2 + 9)^{1.5} \times \frac{x^3}{3} +9x][/tex]

Now we will put the value of limits in the above expression:

First putting the lower limit, i.e. the value of x = 3

We will get it as:

[tex]\frac{1}{1.5}[( 3^2 + 9)^{1.5} \times (\frac{3^3}{3} +9\times 3)]\\\frac{1}{1.5} [18^{1.5}\times (9+27)]\\\frac{1}{1.5} [18^{1.5}\times 36][/tex]

Now putting the value of lower limit, i.e the value of x = 3,

We will get it as:

[tex]\frac{1}{1.5}[( 0^2 + 9)^{1.5} \times ({\frac{0^3}{3} +9\times 0)}]\\\frac{1}{1.5} [9^{1.5}\times ({0+0})]\\\frac{1}{1.5} [9^{1.5}\times 0]=0[/tex]

Now, for detemining the value of the expression,

We will subtract the value of lower limit from upper limit

We will get it as; [tex]\frac{1}{1.5} [18^{1.5}\times 36][/tex]

one of the angles measures greater than 90 degrees (110.01 degrees), this is an obtuse triangle.

An obtuse triangle is a triangle that has one angle which measures greater than 90 degrees. In order to determine if a triangle is an obtuse triangle, we need to calculate its angles.

To calculate the angles of the triangle, we can use the following formula:

Angle 1 = arccos ( (b2 + c2 - a2) / 2bc )

Angle 2 = arccos ( (a2 + c2 - b2) / 2ac )

Angle 3 = arccos ( (a2 + b2 - c2) / 2ab )

In this case, a = 6cm, b = 10cm, and c = 13cm. Substituting these values into the formula, we get:

Angle 1 = arccos ( (102 + 132 - 62) / 2 x 10 x 13 ) = 89.99 degrees

Angle 2 = arccos ( (62 + 132 - 102) / 2 x 6 x 13 ) = 110.01 degrees

Angle 3 = arccos ( (62 + 102 - 132) / 2 x 6 x 10 ) = 89.99 degrees

Since one of the angles measures greater than 90 degrees (110.01 degrees), this is an obtuse triangle.

For weeks before labor starts, the cervix can dilate to 1 centimeter. The cervix is only beginning to prepare for labor at this stage of dilatation.

Every woman experiences a different amount of time between dilation to 1 cm and delivery. While another woman maybe 1-2 cm dilated for days or weeks, one woman may move from having a closed cervix to giving birth in a matter of hours.

Some women don't start dilating until they start laboring actively. This indicates that the cervix is initially fully closed, but as labor goes on, it opens to a diameter of 10 cm. First pregnancies are where it occurs most frequently. Other women, particularly those who have already given birth, may begin dilating days or weeks before the commencement of labor.

The cost of fencing the triangular park  at the rate of  ₹18.50 per meter is ₹4903.65

To find the cost of fencing a triangular park with sides measuring 115m, 81.63m, and 69.27m, we first need to calculate the perimeter of the triangle. The perimeter of any two-dimensional figure is defined as the distance around the figure. We can calculate the perimeter of any closed shape just adding up the length of each of the sides.

Perimeter of triangle= Sum of the three sides

To do this, we add up the lengths of all three sides: 115m + 81.63m + 69.27m = 265.9m.

We can then multiply the perimeter by the cost per meter of fencing to find the total cost: 265.9m * ₹18.50/m = ₹4903.65.

So the cost of fencing the triangular park at the rate of ₹18.50 per meter is ₹4903.65

The other possible length for the third side of the triangle is 15 cm.

What is an Angle Bisector Theorem?

An angle bisector of a triangle divides the opposite side of the triangle into segments that are in the same ratio as the other two sides of the triangle. This is called the Angle Bisector Theorem.

Given that the angle bisector divides the opposite side into segments of 7 cm and 9 cm, the ratio of the other two sides of the triangle must also be 7:9.

Since the second side of the triangle is 22.5 cm, the third side must be:

x = (22.5 * 9) / 7 = 27 cm

So, the third side of the triangle is 27 cm.

The other side can be calculated by using the Pythagorean theorem.

c^2 = a² + b²

b = √(c² - a²)

b = √((27)² - (22.5)²)

b = √(729 - 506.25)

b = √222.75 = 15cm

Hence, The other possible length for the third side of the triangle is 15 cm.

Given that Segment JK has endpoints J(2,4) and K(6,2). You dilate the segment using a dilation centered at the origin with a scale factor of 1/2 and then reflect the image over the x-axis.

Dilation of the point will be,

The table shows a proportional relationship between the cups of milk used and number of tablespoons of chocolate syrup used. The scale factor shown is 3/2. The constant of proportionality for this relationship is 3/2. The units for the constant of proportionality are teaspoons of chocolate syrup used per cups of milk used.

When it comes to ratios and fractions, the concept of proportion is very connected. When two amounts with the same unit are compared, they form a ratio. When comparing two quantities, a ratio enables us to determine whether one is larger or smaller.

Two ratios or two fractions are equivalent when they are compared according to the proportional rule. To put it another way, two ratios are said to be proportional when they are equal. Performing arithmetic operations on both sides of the ratio taught us that a ratio can be expressed in a variety of ways.

Both the 3: 5 and 6: 10 are equivalent ratios. This indicates that these ratios are proportional. This proportionality can be expressed mathematically as follows:

Terminology

Variable: Any letter than stands for a value than can be solved and change value.

Coefficient: The number right before a variable (without being separated by an operator). It is a multiplication factor for a variable. Basically, it's just a way to express what you are multiplying a variable by,

If the coefficient is 1, it means [variable] * 1. 1[variable]

If the coefficient is 3, it means [variable]  * x.  3[variable]

etc.

Constant: A fixed value (i.e. 3, 8, 1928). A variable is not a constant because if you were to add a coefficient (not including 0) to the start of a variable, the result would change depending on the value of the variable.

How to Solve

To solve, you must isolate the variable. It means moving the variable and it's coefficient to the other side of the equation with only the same variable on the same side with all the constants on the other side.

Do this with this rule that is extremely important in ALL of math beyond per-algebra and algebra.

Rule

If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same. That is how you solve for it.

Subtract 4 on both sides to isolate the variable.

8 - 4 = 2x + 4 - 4

Simplify by combining like terms.

4 = 2x

Divide 2 on both sides to solve for x as the coefficient is currently 2.

The rocket’s height to the nearest hundredth when the distance between you and the rocket is 100 feet is equal to 96.83 feet.

Based on the information provided, the height h (in feet), of this rocket during its launching with respect to distance d between you and the rocket can be modeled by this quadratic function:

d(h) = √(625 + h²)

Substituting the given parameters into the quadratic function d(h), we have the following;

d(h) = √(625 + h²)

100 = √(625 + h²)

Taking the square of both sides of the quadratic function, we have the following:

100² = [√(625 + h²)]²

10,000 = 625 + h²

Rocket’s height, h² = 10,000 - 625

The probability of P(26 < X < 30) is 0.48.

In this case, the given parameters are:

Mean μ = 26

Standard deviation σ = 2

So, the probability P(26 < X < 30) will be represented as:

P(26 < X < 30)

= P(z1 < z < z2)

where:

z = (X – μ) / σ

Thus, now we have:

P(26 < X < 30)

= P((26 – 26) / 2 < z < (30 – 26) / 2)

= P(0 / 2 < z < 4 / 2)

= P(z < 2) – P(z < 0)

For z-score of probabilities, we have:

Yes, the sides 5 cm, 12 cm, and 13 cm form a right-angled triangle.

This is because of the Pythagorean Theorem which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, 13 cm is the hypotenuse, and 5 cm and 12 cm are the other two sides.

5^2 + 12^2 = 25 + 144 = 169

13^2 = 169

Since the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, this means that the triangle is indeed a right-angled triangle.
